This book is intended to serve as a medium for dissemination of scientific and technical information emanated from research on soil and water engineering technology to continuing to develop cutting edge technologies for solving numerous engineering and social problems facing agriculture in the world at large. It is also aimed at providing practical guidelines to those who involved in the practice of soil and water conservation, irrigation and drainage, farmers, field assistants, engineers, researchers, students and decision makers. The book contains technical approach to: Impact of soil compaction on Amaranthus vegetable yield and soil bulk density; Determination of crop coefficient of three varieties of tomatoes; Classification of selected irrigation streams; estimation of total surface runoff for minimum and maximum storm; Investigation of rainfall variability; Effects of cow dung, poultry dropping and inorganic fertilizer on soil properties; Impact of industrial effluent discharge on surrounding environment; Spatial variability of chemical and physical soil properties; and Determination of irrigation practices that optimize water application and increase productivity of tomato.
